ELECTR|C CONDUCTOR.

SPBCIFICATICN forming part of Letters Patent No. 304,170, dated August26, 1884.

Application filed April l'. 1884. (No model.)

T (ZZ whom it may concern Be it known that I, FRANCIS D. CADY, ofW'aterbury, in the county of New Haven, and in the State of0onnecticut,have invented certain new and useful Improvements in ElectricConductors; and I do hereby declare that the following is a full, clear,and exact description there0f, reference being had to the accompanyingdrawings, in which- Figure 1 is an enlarged perspective view of asection of my improved conductor, and Fig. 2 is a cross-section of thesame.

Letters of like name and kind refer to like parts in each of thefigures.

lNIy invention has for its object the production of an electricconductor in which are combined a minimum of weight and cost and amaximum of efliciency; to which end it consists in an electric conductorcomposed of strips of metal which are arranged in parallel lines, andare bound together and insulated from each other by means of suitablematerial that is wound around and between said parts,

- substantially as and for the purpose hereinafter specified.

In the construction of my conductor any desired number of metal strips Aare arranged in parallel lines, and are secured together and insulatedfrom each other by means of a suitable flexible material, B, whichpassos spirally between and around said parts, and forms of the whole acable that possesses in a remarkable degree strength and lightness. Eachstrip A possesses a capacity for conducting electricity fully equal tothat of a wire having an equal extent of surface and several times itsweight, and being thoroughly insulated from each of the other stripsaffords a perfect medium for the transmission of an electric current.

For outdoor or underground use the con ductor thus constructed isfurther protected by means of a coat of water-proof material; but foruse in buildings such additional protection is dispensed with.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1s An electric conductor composed of strips of metalarranged in parallel lines, and bound together and insulated from eachother by means of non conducting material that is wound between andaround the strips, substantially as shown and described.

In testimony that I claim the f0regoing I have hereunto set my hand this28th day of March, 1884.

FRANCIS D. CADY.
